There are a couple of lines in there indicating that it also wasn't very accurate as to who is in what gang, sometimes listing the same person in opposing gangs. Given that it seems to indicate that cops can just add people to the list, I'd guess there are people on it who aren't actually affiliated.
It could have gone into more detail, but I do think it points out that the lists are inaccurate. It just focuses mostly on the impact rather than demonstrating that beyond a couple of lines.
